CARRIAGE-PO LE.

SPECIFICATION forming part of Letters Patent No. 422,393, dated March 4, 1890.

Application filed November 25, 1889. Serial No. 331,561. (No model.)

ings, and to the letters of reference marked thereon, which form a part of this specification.

\ This invention relates to carriage-poles and to that class known as adjustable poles, and is designed as an improvement over Letters Patent issued to me February 3, 1880, No. 224,171.

to which the forward ends of the brace-rods are coupled, said head being serrated on its the pole.

under face to engage with the serrated upper face of a plate secured 'to. the under side of The rear ends of the brace-rods are pivotally coupled .to the pole-irons'that are bolted to the outer curved endsof the circle-bars, the inner ends of the circle-bars provided with .metal casings that are journaled in a bearing secured to the rear end of the pole.

The object of the invention is to increase and facilitate the adjustment of the pole, and to make a pole of better appearance and one that is stronger and more durable, all of which will be hereinafter set forth, and the essential features of the device pointed out particularly in the claims. I

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of the'under side of a pole embodying my invention. Fig. 2 is a side elevation. Fig. 3 is an enlarged detached view of the metal case adapted to receive the inner end of the circle-bar. Fig. 4 is an isometrical View of the serrated plate and an inverted plan of the sliding head detached, the brace-rods plate.

clips on the axle of the vehicle.

' the pole; B B, the circle-bars; O C,the bracerods, and G the sliding head. The plate H, having the elongated slot at and serrated upper face If, is bolted to the under side of the pole. The sliding head G, having the -serrated under face t, is set between the pole A and. plate H and is adapted to slide on said The bolt h of the head G extends through the slot a in the plate H and receives on its lower end the washer e and nut e, as shown in Figs. 1 and 2. By tightening said nut e the serrated faces of the head Gr and plate H are drawn together, thus securely locking the parts.

' I11 my patent referred to the plate H is placed 011 the pole with the toothed surface down, and I used atoothed washer to engage with said plate. In this case I turn the toothed plate over and form on the under face of the sliding head a toothed surface of such form as to engage with theteeth or serrations 0f the'plate H, thereby forming a stronger and more practical fastening, using an ordinary washer and nut on the under face of the plate H to complete the fastening. The forward ends of the brace-rods C are attached to the sliding head. The rear diverging ends of said rods are pivotally coupled at i to the circle-bars or pole-irons B,-that are bolted to to the outer curved ends of the circle-bars B B, said pole-irons or extensions B having the heads I) pivotally attached to their rear ends, that are adapted to be coupled to the The inner ends of the circle-bars are provided with a metal case D,the sides of which have the extended malleable ears 0 c. Said casealso has the annular head D, provided with the hole 11. (See Fig. 3.) The end of the circle-bar is secured in the case by bolting through said case and bar, the ears 0 of the sides of the case being bent over onto the under face of the wooden bar B to assist in securing the sides of the case from springing out. The rear end of the pole A is provided with the plates E and F. The plate E lies on the under side of the pole. The curvedarm f of said plate extends along the under face of the pole and lies in the recess a in the rear end of the plate H and'issecured therein by a bolt passing through the pole and the holes .9 and s respectively, in the plate H and arm I do f. Said arm serves to retain in shape the bent portion of the pole. The rear end of the pole lies between the inner faces of the posts Z of the plate E, and extends slightly beyond said plate. The plate I forms a cap for the plate E and rests on the posts Z of said plate.

The plates are held in place and secured to the pole by a bolt passing through the hole cl in the plate 1 through the pole, and through the hole d in the plate E, the arm f of the plate F being bolted to the upper curved face of the pole. The annular heads D of the cases D extend between the adjacent faces of the plates E and F and lie in the concave n of the posts Z, and are pivotally secured therein by bolts or rivets passing through the holes 1) in the plate F, through the holes 1) in the annular head, and through the holes o" in the plate E, thus permitting said heads to rotate in the plates as the circle-bars are moved in adjusting the pole.

To adjust the pole fora narrow vehicle, the nut e is loosened and the head Gslid toward the rear end of the pole, carrying the brace-' irons E 1* attached to the rear end thereof,

rods back and swinging in the free ends of the circle-bars, as clearly shown by dotted lines in Fig. 1. To adjust the pole for a wide vehicle, the head G is moved in the opposite direction, as will be readily understood. \Vhcn the pole is adjusted to the proper width, the nut e is tightened, which securely locks the sliding head G and holds the bracerods 0, whereby the circle-bars are firmly braced. By pivoting the brace-rods to the circle-bars the adjustment is greatly facilitated and the circle-bars uniformly adjusted.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the pole, the twopart circle-bar, the inner ends thereof having a metal casing D, said casings having a pivotal connection with the rear end of the pole, and the brace-rods pivotally coupled to the circlebar at their rear ends, their forward ends attached to the sliding head, said sliding head adjustably coupled to the pole, substantially as and for the purposes set forth.

2. In combination with the pole having the metal coupling-plates E and F attached to the rear end thereof, the two-part circle-bar, the inner ends thereof having a pivotal coupling with the coupling-plates of the pole,the set of metal extensions mounted on the free ends of the circle-bar, and the brace-rods having a pivotal connection with said extension-iron s, their forward ends being coupled to the traveling head mounted on the pole, said traveling head adapted to be locked when adjusted, as and for the purposes specified.

3. In combination with the pole having the irons E and F mounted on the rear end thereof, the two-part wooden circle-bar, and the metal cases D, attached to the inner ends thereof,

. said cases having a pivotal connection with the irons mounted on the rear end of the pole, the free or outer ends of the circle-bar adapted to be swung toward or from each other.

4. In combination with the pole having the the two-part wooden circle-bar, the inner ends thereof having the metal casings D, which casings are pivotally coupled to the irons on the rear end of the pole, the brace-irons hav-' ing their rear ends pivotally coupled to the I circle-bar, their forward ends coupled to the sliding head, the toothed and slotted plate attached to the under face of the pole, the traveling head having the toothed face t, which engages with the toothed face of said plate, the bolt attached to the traveling head and passing through the slot at of the plate, and nut, whereby said parts are locked when adjusted.

In testimony whereof I alfix my signature in presence of two witnesses.
